Generation of Orchard and Tree-Child Networks
Bull Math Biol. 2023 Dec 20;86(1):10. doi: 10.1007/s11538-023-01239-z.ABSTRACTPhylogenetic networks are an extension of phylogenetic trees that allow for the representation of reticulate evolution events. One of the classes of networks that has gained the attention of the scientific community over the last years is the class of orchard networks, that generalizes tree-child networks, one of the most studied classes of networks. In this paper we focus on the combinatorial and algorithmic problem of the generation of binary orchard networks, and also of binary tree-child networks. To this end, we use that these networks are d...

Dynamics of a Mosquito Egg-Larvae Model with Seasonality
Bull Math Biol. 2023 Dec 18;86(1):9. doi: 10.1007/s11538-023-01238-0.ABSTRACTWe propose a two stages mosquito egg-larvae model with seasonality as a simplification of a four stages one. For the simplified model we characterize the dynamics in terms of the vectorial reproduction number, [Formula: see text], obtaining extinction if [Formula: see text] and convergence to a unique positive periodic orbit if [Formula: see text]. We illustrate each case with an example, by providing general conditions on the periodic coefficients for its occurrence. These examples are further developed using numerical simulations where the perio...

Models for Implant-Induced Capsular Contracture Post Breast Cancer Surgery
Bull Math Biol. 2023 Dec 13;86(1):7. doi: 10.1007/s11538-023-01236-2.ABSTRACTCapsular contracture is a painful deformation of scar-tissue that may form around an implant in post-breast cancer reconstruction or cosmetic surgery. Inflammation due to surgical trauma or contamination in the tissue around the implant could account for recruitment of immune cells, and transdifferentiation of resident fibroblasts into cells that deposit abnormally thick collagen. Here we examine this hypothesis using a mathematical model for interacting macrophages, fibroblasts, myofibroblasts, and collagen. Our model demonstrates that cellular r...

Formation and Growth of Co-Culture Tumour Spheroids: New Compartment-Based Mathematical Models and Experiments
Bull Math Biol. 2023 Dec 13;86(1):8. doi: 10.1007/s11538-023-01229-1.ABSTRACTCo-culture tumour spheroid experiments are routinely performed to investigate cancer progression and test anti-cancer therapies. Therefore, methods to quantitatively characterise and interpret co-culture spheroid growth are of great interest. However, co-culture spheroid growth is complex. Multiple biological processes occur on overlapping timescales and different cell types within the spheroid may have different characteristics, such as differing proliferation rates or responses to nutrient availability. At present there is no standard, widely-ac...
